After I get done emerging and installing grub2 with no errors, I then proceed with 10.e. Rebooting the System. When the system reboots I no longer have network connectivity and my wired (enp0s20u1) and wireless (enp025) devices are gone.

I tried again this morning using genkernel and it works like a charm, except I don't see my wireless card (again). So the logical conclusion is that something I'm adding to the kernel is killing my network.

For the wired interface you need e1000e in the kern, or made as a module and the module loaded.

Its unusual for your interfaces to vanish when you chroot, since they are always provided by the host system outside the chroot.
Does

Code:

ifconfig

givue different results inside and outside the chroot?
You can test both at the same time ...
Boot your liveCD
Issue the passwd command and set the root password to something you know. You will need this password later.
Mount everything and get into the chroot.
Press Ctl-F2 to switch to Virtual Terminal (VT) 2.
Log in as root, using the password you just set.
You now have VT1 (ctl-F1) inside the chroot and VT2, where you are now outside the chroot. You have VT1 ... VT5 like this. Ctrl-Fx switches between them.
You can even copy/paste between VTs too.

Its quite common for networking to vanish when you chroot but not the interfaces.
No networking in the chroot is usually the result of not copying /etc/resolv.conf to /mnt/gentoo/etc/resolv.conf before chrooting.
Have a look in /etc/resolv.conf in both of your VTs._________________Regards,

NeddySeagoon,

I thought I'd post an update as I figured out what I was doing wrong.

The first thing I did wrong, and kept doing wrong was leaving the mount options as "noauto" in /etc/fstab, instead of "defaults" as depicted in the handbook.

Another thing I was doing wrong was using my USB to RJ-45 adapter instead of the built-in network adapter. Once I corrected my network settings to show the proper interface all was well with my wired connection.
